He only ever regurgitated when I put him in a feeder box. So just once. Never since then. For a few days he was very active, and defensive. Then I fed him, he went into his hide and was still aggressive. Fed him again and still seemed to be acting off. So I fed a f/t and he ate that, and still hasn't regurgitated. So I don't think I overfed him. My concern is he will never go back to his docile self.
